The authors conclude that the STT-1 is an accurate assessment of tear production in cats. They further conclude that values at time <1 minute may be used to accurately predict values at 1 minute.
The measurement of tear production is an important diagnostic test when deficiency of the lachrymal system is suspected. The Schirmer tear test (STT) devised by Otto Schirmer a century ago is widely used in both human and veterinary ophthalmology as a basic assessment of tear production . Two types of STTs have been developed: STT I and STT II.The SCHIRMER TEAR Test (STT) is a diagnostic test that is indicated to measure the rate of tear production. It should be used in the evaluation of conjunctivitis to diagnose tear deficiency as a contributing factor to ocular . A Schirmer tear test (STT) is used to determine if the eyes are producing adequate amounts of tears; therefore, it is the preferred test for diagnosing KCS. How Is a Schirmer Tear Test Performed?

Background: The Schirmer tear test (STT) is widely used in both human and veterinary ophthalmology. Two types of STTs have been developed: STT I and SST II. The STT I measures the basal and reflex tear production and is the most widely used STT. However, several factors influence the STT results such as the person performing the test and the .Schirmer Tear Test (STT) The Schirmer Tear Test (STT) is used to determine the rate of tear production in pets. Tears are produced in the lacrimal gland and the gland of the third eyelid. Tears are important to keep the eyes healthy. If the glands do not produce enough tears, it can increase your pet’s risk of developing keratoconjunctivitis .
The Schirmer tear test (STT) is used to quantitatively measure tears produced by the lacrimal gland during fixed time period in patients suspected of having DED. 10 The STT I test measures total tear production, including both the basal and reflex tears. 69 The test is performed by inserting Schirmer tear strips into the lower conjunctival sac .Schirmer's Tear Test is an essential diagnostic tool used in optometry to assess tear production and evaluate ocular surface health. This simple yet effective test measures the volume of tear production over a specified time, providing critical insights into the function of the lacrimal gland.The Schirmer tear test (STT) measures basal tear production and reflex tear response and is often used to diagnose keratoconjunctivitis sicca (KCS). cl,ss="intro-deck"> 1sup> Basal tears are normal tears produced daily to lubricate and nourish .The most common tear production test is the Schirmer tear test (STT). This simple test uses a special wicking paper to measure the amount of tear film produced in one minute. Additional diagnostic tests may include corneal staining to check for corneal ulcers, intraocular pressure (IOP) to determine if glaucoma is present, and tear duct .
The diagnosis is easily confirmed by using the Schirmer tear test (STT). The STT, a quick and easy test, should be performed as a routine part of the ophthalmic examination in any dog, but it must be used in every dog of a predisposed breed with conjunctivitis, even with no other clinical signs of dry eye.
The Schirmer tear test 1 (STT-1) is considered the standard method for quantifying aqueous tear secretion in dogs and other species, 1-4 providing information about the subject's basal tearing, reflex tearing, and lacrimation kinetics. 5, 6 In clinical practice, STT-1 is often repeated at different visits over time; as such, it is important for .Schirmer Tear Test. The Schirmer tear test I (STT) is a method of measuring basal and reflex tear production in animals when deficient tear volume (aqueous component) is suspected. It is performed by inserting a sterile filter paper strip into the lower, middle conjunctival fornix of each eye. The strip is inserted and left in place for 60 .
In this VETgirl video, we are demonstrating a Schirmer Tear Test (STT) in a dog. This test measures the tear production by the lacrimal gland and the gland of the 3rd eyelid. Any patient with ocular discharge or redness should have this test performed. This test should be performed PRIOR to any drops being instilled on the eye.The Schirmer Tear Test (STT) remains the gold standard for the diagnosis of KCS. There are 2 types of STT. The STT I test is done without local anaesthetic, and therefore measures both the basal and reflex components of the tear film. In the STT II test topical anaesthetic is applied so the STT II will only measure the basal component of the . The Schirmer tear test (STT) can help determine if low tear production is an underlying cause or a contributing factor to an cat’s eye problem. Low tear production can cause significant eye inflammation and chronic eye problems. A Schirmer tear test is indicated anytime an animal has a reddened eye or has thick discharge from the eye.

Early KCS: 11-14 mm wetting/minute. Moderate KCS: 6-10 mm wetting/minute. Severe KCS: <5 mm wetting/minute
Routine baseline tests like the Schirmer tear test (STT), fluorescein staining, and tonometry (intraocular pressure [IOP] measurement) are generally performed next.
